Nipple Shield with Port and Flap-Covered Channel to Supplement Lactation During Breastfeeding

ABSTRACT

Nipple shields can be used by breastfeeding mothers to facilitate the feeding process. The disclosed embodiments relate to nipple shields with a port through which liquid supplement can flow from a supply tube into an interior section of the shield. The liquid supplement can be drawn through ports in a tip of the shield in order to augment a naturally expressed flow of milk. A flap of material is bonded to an interior portion of the nipple shield over an optional channel formed in the interior portion so as to form a closed, flap-covered channel leading from an input port on a lower portion of the shield to a an interior location near the tip of the shield.

DETAILED DESCRIPTION

In the following description, references are made to various embodiments in accordance with which the disclosed subject matter can be practiced. Some embodiments may be described using the expressions one/an/another embodiment or the like, multiple instances of which do not necessarily refer to the same embodiment. Particular features, structures or characteristics associated with such instances can be combined in any suitable manner in various embodiments unless otherwise noted. By way of example, this disclosure may set out a set or list of a number of options or possibilities for an embodiment, and in such case, this disclosure specifically contemplates all clearly feasible combinations and/or permutations of items in the set or list.

Nipple shields can be used by breastfeeding mothers to facilitate the feeding process. In accordance with various embodiments, a nipple shield can include a port through which liquid supplement can flow from a supply tube into an interior section of the shield. The liquid supplement can be drawn through ports in a tip of the shield in order to augment a naturally expressed flow of milk.

A flap of material is shown extending from the shield in the second embodiment, and that is bonded, in the assembled first embodiment, to an interior portion of the nipple shield over a channel formed in the interior portion of the shield so as to form a closed channel leading from the port to a location near an interior tip of the shield. The flap of material is also shown bonded in place in the third embodiment in FIG. 31.

In accordance with various embodiments, a nipple shield can include the following features. The nipple shield can include a tip section having an interior surface, an exterior surface and one or more perforations passing through the tip section between the interior surface and the exterior surface. The nipple shield can include a substantially frustoconical-shaped middle section having an upper portion adjoining the tip section and a lower portion opposite the upper portion, the upper portion having a diameter less than the lower portion, the middle section having a substantially frustoconical-shaped interior surface that adjoins the interior surface of the tip section, the middle section having a substantially frustoconical-shaped exterior surface that adjoins the exterior surface of the tip section, the middle section having an open channel formed along the interior surface and extending from the lower portion to the upper portion of the middle section. The nipple shield can include a lower section having an upper portion adjoining the middle section and a lower portion opposite the upper portion, the lower section having an interior surface that adjoins the interior surface of the middle section, the lower section having an exterior surface that adjoins the exterior surface of the middle section, the lower section having an open port passing between the interior surface and the exterior surface. The nipple shield can include a supply tube adjoining the lower section at the open port forming a passage through the supply tube to the interior surface of the lower section. The nipple shield can include a channel cover of thin flexible sheet material, the channel cover being bonded, joined, affixed or sealed to portions of the interior surface of the lower section to cover the open port, the channel cover being bonded, joined, affixed or sealed to portions of the interior surface of the middle section to cover a portion of the open channel, wherein the bonded, joined, affixed or sealed portions of the channel cover extend along an interior surface of the nipple shield from the open port and along two sides of the channel to a location proximate the tip section.

In one embodiment, the interior surface of the tip section is concave and the exterior surface of the tip section is convex.

In one embodiment, the tip section, the middle section and the lower section are formed of silicone rubber.

In one embodiment, the tip section, the middle section, the lower section, the supply tube, and the channel cover are formed of silicone rubber.

In one embodiment, the channel cover is formed of a flap of material that is molded contiguously with at least the lower section, and wherein the molded flap is subsequently bonded to the middle section along two sides of the channel.

In one embodiment, the channel is omitted from the shield, such that the interior surface of the middle section does not include a channel, such that the channel cover is not bonded to the interior of the middle section along a path where the channel would otherwise be located, and such that a stream of supplement can create a gap and flow under pressure in an unbonded area between the channel cover and the interior surface of the middle section.

Although the subject matter has been described in terms of certain embodiments, other embodiments that may or may not provide various features and aspects set forth herein shall be understood to be contemplated by this disclosure. The specific embodiments described above are disclosed as examples only, and the scope of the patented subject matter is defined by the claims that follow. In the claims, a portion shall include greater than none and up to the whole of a thing.

 2. The nipple shield of claim 1, wherein the interior surface of the tip section is concave and the exterior surface of the tip section is convex.
 3. The nipple shield of claim 1, wherein the tip section, the middle section and the lower section are formed of silicone rubber.
 4. The nipple shield of claim 3, wherein the tip section, the middle section, the lower section, the supply tube, and the channel cover are formed of silicone rubber.
 5. The nipple shield of claim 4, wherein the channel cover is formed of a flap of material that is molded contiguously with at least the lower section, and wherein the molded flap is subsequently bonded to the middle section along two sides of the channel.
